在OS X上使用pip重新安装numpy“无法修改或删除，因为它是OS X所需的”

Question

我试图升级macOS上的numpy库，但是pip似乎没有足够的权限删除numpy。运行`pip install--upgrade pip会给我以下回溯：

➜  Desktop sudo -H pip install --upgrade numpy

    DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling numpy-1.8.0rc1:

所以显然pip在删除/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info时遇到了麻烦。尝试在finder中手动删除此文件时出现以下错误：

“numpy-1.8.0rc1-py2.7.egg-info” can’t be modified or deleted because it’s required by OS X.

我怎么解决这个问题？（使用内置numpy不是一个选项，因为我需要的包tensorflow需要最新版本）。在
